Abstract

A sintered oxide ceramic of specified formula is produced by sintering educts with a doping element. Production of a sintered oxide ceramic of formula: CexMyDzO2-a M = rare earth element, but not Ce, alkali and alkaline earth metal D = a metal is not the same as M comprises sintering educts with a second doping element D selected from Cu, Co, Fe, Ni and Mn in the submicron particle size or as salt solution and at a temperature of 750-1250o C to form an oxide ceramic with extremely fine structure of grain size of not more than 0.5 microns.
